Description

Technical Field

[0001] The present application belongs to the field of display technology, and specifically relates to a bracket, an assembly device and a display device. Background Art

[0002] In the display screen, the outdoor display module needs to be equipped with a protective cover to protect the lamp beads. In the production process of outdoor display modules, an automatic screw locking machine is required to fix the protective cover to the display module with screws. However, when assembling the protective cover, the automatic screw locking machine moves down, which will compress the display module to deform, causing part of the protective cover to bulge. When the light passes through the bulging position, the light intensity changes, resulting in inconsistent color of the display. Especially when the display screen is turned off, under natural light, when the light reflected by the lamp beads passes through the bulging position of the protective cover, black spots will appear on the display screen. Utility Model Content

[0003] The purpose of the present application is to provide a bracket, an assembly device and a display device, which can effectively reduce the bulging deformation of the protective cover relative to the display module, ensure the color consistency of the display screen, and reduce black spots when the screen is turned off.

[0028] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this application will be more comprehensive and complete and fully convey the concept of the example embodiments to those skilled in the art.

[0029] See also Figure 1 and Figure 2 As shown, the present application provides a bracket, which includes: a support structure 100 and a buffer structure 200. The buffer structure 200 is disposed on the support structure 100, so as to perform pressure buffering on the display module 300 placed on the support structure 100.

[0030] Specifically, the support structure 100 is formed with a bearing space 101, and the bearing space 101 is used to place the display module 300 and the protective cover 400 located above the display module 300; the size and shape of the bearing space 101 are adapted to the outer dimensions of the display module 300 to ensure that the display module 300 can be placed therein, and the bearing space 101 can also limit the translation of the display module 300 to avoid the display module 300 being forced to translate due to the excessive size of the bearing space 101. Once the display module 300 translates, the display module 300 may be misaligned with the protective cover 400. Of course, in order to avoid the support structure 100 and the display module 300 being installed too tightly, or even squeezing the display module 300, or the display module 300 cannot be placed in the bearing space 101, the bearing space 101 can be set slightly larger, for example, the lateral dimension of the bearing space 101 is 20 mm larger than the display module 300. In this way, the display module 300 can be installed in the carrying space 101 , and arbitrary translation of the display module 300 can be avoided.

[0031] In addition, the support structure 100 can be made of metal, such as aluminum alloy. The support structure 100 can half-wrap the display module 300, protect the side and bottom of the display module 300, and reduce the damage to the display module 300 when the protective cover 400 is fixed. In addition, the protective cover 400 is usually transparent to reduce the blocking of light from the display module 300. The display module 300 is provided with lamp beads, and the protective cover 400 can protect the lamp beads and reduce the damage of the lamp beads.

[0032] The buffer structure 200 is disposed on the support structure 100 and is located in the bearing space 101. The buffer structure 200 is used to buffer the display module 300 so as to reduce the deformation of the display module 300 when the protective cover 400 is fixed to the display module 300. For example, the protective cover 400 is fixed to the display module 300 by screws. When the screw locking mechanism drives the screws to approach the protective cover 400, it will apply a fixing force on the protective cover 400 so that the protective cover 400 fits the upper surface of the display module 300. The fixing force applied by the screw locking mechanism is transmitted to the display module 300 through the protective cover 400, and further transmitted to the buffer structure 200 through the display module 300. The buffer structure 200 can withstand the fixing force, so that the fixing force acts on the buffer structure 200, and avoids the fixing force acting on the display module 300.

[0033] In this embodiment, the display module 300 is carried by the support structure 100, and the protective cover 400 is arranged above the display module 300. When the protective cover 400 is fixed on the display module 300, the buffer structure 200 can buffer the display module 300 and withstand the fixing pressure applied to the display module 300. The fixing pressure will be transferred to the buffer structure 200, thereby preventing the display module 300 from deforming, so that the protective cover 400 fits tightly on the upper surface of the display module 300, and the display module 300 and the protective cover 400 are fixed smoothly. There will be no bulging between the protective cover 400 and the display module 300, which reduces the generation of space gaps, and light will not be absorbed when passing through this position. It can be seen from this that the technical solution of the present application can reduce the bulging deformation of the protective cover 400 relative to the display module 300, ensure the color consistency of the display screen, and especially reduce the black spots when the screen is turned off, so that the color of the display screen can remain consistent even when the screen is turned off.

[0034] At the same time, by providing the buffer structure 200 , the mutual misalignment between the protection cover 400 and the display module 300 can be reduced, further ensuring the display color consistency of the display screen.

[0035] In order to give full play to the buffering effect of the buffer structure 200, the buffer structure 200 includes an elastic member 210, one end of the elastic member 210 is abutted against the bottom end of the bearing space 101, and the other end is used to connect the display module 300. The fixing force from the display module 300 is transmitted to the elastic member 210, and the elastic member 210 is deformed under pressure. In other words, the fixing force acting on the display module 300 is transferred to the elastic member 210, and the deformation of the display module 300 is reduced by the deformation of the elastic member 210. It can also be considered that the deformation of the display module 300 is transferred to the elastic member 210. Moreover, when the elastic member 210 is deformed by pressure, it can still return to its original shape after the pressure is removed, and can bear the next application of the fixing force, and can be recycled for many times.

[0036] In the present application, the buffer structure 200 also includes a buffer block 220, which is arranged on the bottom side of the elastic member 210 away from the bearing space 101, and the end of the buffer block 220 away from the elastic member 210 is used to abut the display module 300. The contact between the buffer block 220 and the display module 300 is a surface-to-surface contact. By setting the buffer block 220, the contact area between the buffer structure 200 and the display module 300 can be increased, and the fixing force applied to the display module 300 can be more smoothly transferred to the elastic member 210. In addition, by setting the buffer block 220, the display module 300 can be placed more stably and the translation of the display module 300 can be reduced. In addition, the buffer block 220 can be a material with a harder texture or a material with a softer texture. For example, the buffer block 220 can be a metal block or a plastic block.

[0037] See also Figure 3 As shown, in another embodiment of the present application, the buffer block 220 includes a first buffer portion 221 and a second buffer portion 222. The first buffer portion 221 is arranged on the side of the second buffer portion 222 facing the elastic member 210. The cross-sectional area of ​​the second buffer portion 222 is greater than the cross-sectional area of ​​the first buffer portion 221. It can be understood that the cross-sectional size of the second buffer portion 222 is greater than the cross-sectional size of the first buffer portion 221. The first buffer portion 221 is arranged on the lower surface of the second buffer portion 222, so that the edge area of ​​the lower surface of the second buffer portion 222 is exposed. For example, the first buffer portion 221 can be arranged at the center of the lower surface of the second buffer portion 222, and the exposed portion of the lower surface of the second buffer portion 222 is arranged in an annular shape. The elastic member 210 is sleeved on the outer side surface of the first buffer portion 221 and abuts against the lower surface of the second buffer portion 222. The elastic member 210 can be a spring, and the first buffer portion 221 and the second buffer portion 222 can be cylindrical. The elastic member 210 surrounds the outer side surface of the first buffer portion 221.

[0038] One end of the elastic member 210 may abut against the support structure 100, and the other end may abut against the second buffer portion 222. The abutting arrangement makes it flexible and convenient to install the elastic member 210. Alternatively, one end of the elastic member 210 may be fixed on the support structure 100, and the other end may be fixed on the second buffer portion 222. The fixed arrangement may fix the buffer structure 200 on the support structure 100 to prevent the buffer structure 200 from falling off. By sleeve-mounting the elastic member 210 on the first buffer portion 221, the connection area between the elastic member 210 and the buffer block 220 may be increased, so that the buffer block 220 can better squeeze the elastic member 210, and the elastic member 210 may be pressed downward and deformed.

[0039] In order to maintain the position stability of the elastic member 210, the support structure 100 is formed with a sinking hole 102, which is arranged at the bottom end of the bearing space 101 and connected to the bearing space 101, and the elastic member 210 is arranged in the sinking hole 102. The sinking hole 102 can fix the position of the elastic member 210, prevent the elastic member 210 from translating left and right, or prevent the elastic member 210 from swinging left and right, and can also ensure that the deformation direction of the elastic member 210 is deformation in the up and down direction. Among them, the buffer block 220 can be partially arranged in the sinking hole 102 to cover the opening position of the sinking hole 102, for example, the first buffer part 221 is located in the sinking hole 102, and part of the structure of the second buffer part 222 is covered in the sinking hole 102.

[0040] See also Figure 2 and Figure 4As shown, further, the bracket also includes a guide wall 500, which is arranged on the support structure 100 and is arranged around the opening edge of the sink hole 102. The guide wall 500 forms a guide cavity with two ends connected, one end of the guide cavity is connected to the sink hole 102, and the other end is connected to the bearing space 101. The guide wall 500 can guide the deformation direction of the elastic member 210, so that the buffer block 220 moves in the up and down direction, ensuring that the deformation direction of the elastic member 210 is also in the up and down direction. Through the setting of the guide cavity, the buffer block 220 can not only move along the direction of the sink hole 102, but also move along the direction of the guide cavity, and can guide the moving direction of the buffer block 220 over a longer distance, ensuring that the fixing force can be accurately applied to the elastic member 210. The guide wall 500 can be welded in the bearing space 101 of the support structure 100, or it can be integrally formed with the support structure 100.

[0041] In order to make the buffer structure 200 buffer the deformation of the display module 300 more uniformly, a plurality of buffer structures 200 are provided, and the plurality of buffer structures 200 are evenly distributed at the bottom of the bearing space 101. The buffer structure 200 can withstand the downward pressure fixing force of the display module 300 in multiple directions, reduce the deformation of some positions of the display module 300, and can buffer the fixing force at multiple positions of the display module 300. In addition, the buffer structure 200 can also be arranged more densely to buffer the force of the entire display module 300 and improve the buffering effect.

[0042] The present application also provides an assembly device, which includes a load-bearing platform and a locking nail mechanism, wherein the locking nail mechanism is disposed above the load-bearing platform, and the assembly device further includes a bracket, which is disposed on the load-bearing surface of the load-bearing platform and is located below the locking nail mechanism. When fixing, the locking nail mechanism drives the screw to approach the protective cover 400, aligns the connection hole between the protective cover 400 and the display module 300, and rotates the screw into the connection hole to complete the fixing of the protective cover 400 and the display module 300.

[0043] The bracket includes: a support structure 100 and a buffer structure 200. The support structure 100 is formed with a bearing space 101, which is used to place the display module 300 and the protective cover 400 located above the display module 300; the support structure 100 can half-wrap the display module 300, protect the side and bottom of the display module 300, and reduce the damage to the display module 300 when fixing the protective cover 400. In addition, the protective cover 400 is usually transparent to reduce the blocking of light from the display module 300. The protective cover 400 can protect the lamp beads and reduce the damage of the lamp beads.

[0044] The buffer structure 200 is disposed on the support structure 100 and is located in the bearing space 101 . The buffer structure 200 is used to buffer the display module 300 so as to reduce deformation of the display module 300 when the protection cover 400 is fixed to the display module 300 .

[0045] In the assembly device of this embodiment, the support structure 100 is fixed by the bearing platform, the display module 300 is carried by the support structure 100, and the protective cover 400 is arranged above the display module 300. When the protective cover 400 is fixed on the display module 300, it bears the fixing pressure applied to the display module 300, and the fixing pressure will be transferred to the buffer structure 200, thereby preventing the display module 300 from deforming, making the protective cover 400 tightly fit on the upper surface of the display module 300, and successfully completing the fixing of the display module 300 and the protective cover 400. In this way, the bulging deformation of the protective cover 400 relative to the display module 300 can be reduced, and the color of the display screen can be ensured to be consistent, especially the black spots when the screen is turned off, so that the color of the display screen can be kept consistent even when the screen is turned off.

[0046] Other specific implementations and beneficial effects of the assembly device refer to the above-mentioned bracket solution and will not be described in detail here.

[0047] The present application also provides a display device, which includes a display module 300 , a protective cover 400 and a bracket. The display module 300 is disposed in a bearing space 101 of the bracket, and the protective cover 400 is disposed on a light emitting surface of the display module 300 .

[0048] The bracket can be understood as a part of the structure of the display device, and the bracket includes: a support structure 100 and a buffer structure 200. The support structure 100 is formed with a bearing space 101, and the bearing space 101 is used to place the display module 300 and the protective cover 400 located above the display module 300; the buffer structure 200 is arranged on the support structure 100 and located in the bearing space 101, and the buffer structure 200 is used to buffer the display module 300, so as to reduce the deformation of the display module 300 when the protective cover 400 is fixed to the display module 300.

[0049] In the display device of this embodiment, each display module 300 is provided with a bracket matched therewith, and the display module 300 is carried by the support structure 100 of the bracket, and the protective cover 400 is arranged above the display module 300. When the protective cover 400 is fixed on the display module 300, it bears the fixing pressure applied to the display module 300, and the fixing pressure will be transferred and applied to the buffer structure 200, thereby preventing the display module 300 from being deformed, so that the protective cover 400 is tightly attached to the upper surface of the display module 300, and the display module 300 and the protective cover 400 are fixed smoothly. In this way, the bulging deformation of the protective cover 400 relative to the display module 300 can be reduced, and the color of the display screen can be ensured to be consistent, especially the black spots when the screen is turned off can be reduced, so that the color of the display screen can be kept consistent even when the screen is turned off.

[0050] See also Figure 4 As shown, the display device further includes a limiting column 600, which is arranged on the lower surface of the display module 300. The limiting column 600 is used to limit the downward movement distance of the display module 300 when the display module 300 moves toward the bottom of the bearing space 101. By setting the limiting column 600, it is possible to prevent the display module 300 from moving downward too far, and to prevent the display module 300 from hitting the bottom of the support structure 100. For example, the height of the limiting column 600 is greater than the height of the guide wall 500, and the limiting column 600 can also have a certain elasticity to prevent the limiting column 600 from rigidly contacting the support structure 100.
